Application of neutrophil-lymphocyte ratio and red blood cell distribution width in diabetes mellitus complicated with heart failure.

BACKGROUND: Accumulating clinical evidence has shown that diabetes mellitus (DM) is a serious risk factor for cardiovascular disorders and an important factor for adverse cardiovascular events. AIM: To explore the value of the combined determination of the neutrophil-lymphocyte ratio (NLR) and red blood cell distribution width (RDW) in the early diagnosis and prognosis evaluation of DM complicated with heart failure (HF). METHODS: We retrospectively analyzed clinical data on 65 patients with type 2 DM (T2DM) complicated with HF (research group, Res) and 60 concurrent patients with uncomplicated T2DM (control group, Con) diagnosed at Zhejiang Provincial People's Hospital between January 2019 and December 2021. The NLR and RDW values were determined and comparatively analyzed, and their levels in T2DM + HF patients with different cardiac function grades were recorded. The receiver operating characteristic (ROC) curves were plotted to determine the NLR and RDW values (alone and in combination) for the early diagnosis of HF. The correlation between NLR and RDW with the presence or absence of cardiac events was also investigated. RESULTS: Higher NLR and RDW levels were identified in the Res vs the Con groups (P < 0.05). The NLR and RDW increased gradually and synchronously with the deterioration of cardiac function in the Res group, with marked differences in their levels among patients with grade II, III, and IV HF (P < 0.05). ROC curve analysis revealed that NLR combined with RDW detection had an area under the curve of 0.915, a sensitivity of 76.9%, and a specificity of 100% for the early diagnosis of HF. Furthermore, HF patients with cardiac events showed higher NLR and RDW values compared with HF patients without cardiac events. CONCLUSION: NLR and RDW were useful laboratory indicators for the early diagnosis of DM complicated with HF, and their joint detection was beneficial for improving diagnostic efficiency. Additionally, NLR and RDW values were directly proportional to patient outcomes.

TyG index is a predictor of all-cause mortality during the long-term follow-up in middle-aged and elderly with hypertension.

BACKGROUND: The triglyceride and glucose (TyG) index has been found to be significantly associated with a higher risk of mortality. However, there has been a lack of studies exploring the specific relationship between the TyG index and all-cause and cardiovascular mortality among middle-aged and elderly with hypertension. METHODS: A total of 3,614 participants with hypertension were enrolled from the National Health and Nutrition Examination Survey. The TyG index was calculated using the formula log [fasting triglycerides (mg/dL) x fasting glucose (mg/dL)/2]. The Cox proportional hazard ratios were used to evaluate the association between the TyG index and the risk of mortality. RESULTS: Over a follow-up period of 7.87 years, 991 all-cause death and 189 cardiovascular deaths occurred. Compared with the reference quartile, the multivariate-adjusted hazard ratios and 95% confidence intervals were 1.28 (1.07-1.53; p = .006) in the fourth quartile for all-cause mortality and 0.63 (0.42-0.96; p = .031) in the second quartile for cardiovascular mortality. Dose-response analysis indicated an L-shaped relationship. CONCLUSIONS: The TyG index exhibited an L-shaped association with the risk of all-cause mortality among middle-aged and elderly with hypertension.

Genome Analysis of ST1 Bartonella henselae, a Zoonotic Pathogen Causing Endocarditis in an Elderly Patient in China.

Infective endocarditis (IE) is a rare disease but with high associated mortality. Currently, the mainstays of diagnosis are still echocardiography and blood cultures. Here, we reported a case of infective endocarditis with negative blood cultures, and blood and aortic valve tissue metagenomic next-generation sequencing (mNGS) results suggested Bartonella henselae. In addition, we obtained the whole genomic sequence of B. henselae ZJBH strain. To our knowledge, this is the first report of B. henselae genomic analysis isolated from clinic in China. Furthermore, we described the whole genome sequencing (WGS) data incorporating all B. henselae from diverse sources worldwide and shed light on underlying risk of B. henselae transmitted between cats and humans.

Expression of S100 proteins is associated with HBV intrauterine transmission.

PURPOSE: The mechanisms underlying HBV intrauterine transmission remain unknown. In this study, we explored the mechanism of HBV intrauterine transmission by iTRAQ proteomics analysis. METHODS: iTRAQ technology was applied to perform comparative proteomics studies on six HBV+/+ neonates and six HBV+/- neonates whose mothers and fathers were HBsAg positive and paternal HBsAg negative, respectively. The data obtained from the mass spectrometer were analyzed using MASCOT ( https://matrixscience.com ) to qualitatively and quantitatively compare the differentially expressed proteins in the two groups. Gene Ontology and KEGG pathway analyses were performed to analyze the differentially expressed proteins. The expressions of HBV intrauterine transmission-related proteins in serum samples and corresponding placental tissues were further verified by immunohistochemistry and Western Blot. Then, the human trophoblast cell line (Swan71) infected with HBV was used to analyze the potential mechanisms of HBV intrauterine transmission under the mediation of differential proteins. RESULTS: A total of 35 differentially expressed proteins, including 17 up-regulated proteins and 18 down-regulated proteins, were identified by comparing serum protein expression levels in HBV+/+ and HBV+/- neonates. The differentially expressed proteins were mainly related to RAGE receptor binding, NF-kappa B transcription factor activity, innate immune response, defense response to bacterium, and the signaling pathway in pathogenic microorganism infection. The expressions of S100A8/9/12 in HBV+/+ maternal placenta tissue were significantly increased. The expressions of S100A8/9/12 proteins in Swan71 cells were significantly increased after HBV infection. CONCLUSION: High expression of S100 proteins may be associated with the intrauterine-transplacental transmission of HBV.

Linking atrial fibrillation with non-alcoholic fatty liver disease: potential common therapeutic targets.

Non-alcoholic fatty liver disease (NAFLD) and atrial fibrillation (AF) are common chronic non-infectious diseases with rising incidences. NAFLD is an independent risk factor for the onset of AF, after adjusting potentially related factors. The pathogenesis of these diseases share several mechanisms including reduced adiponectin level, insulin resistance, and renin angiotensin aldosterone system (RAAS) activation, in addition to activation of common disease pathways that promote inflammation, oxidative stress, and fibrosis. Furthermore, statins and RAAS blockers exert therapeutic effects concurrently on NAFLD and AF. The common pathogenesis of NAFLD and AF may serve as a potential therapeutic target in the future.

The regulation of immune cells by Lactobacilli: a potential therapeutic target for anti-atherosclerosis therapy.

Atherosclerosis is an inflammatory disease regulated by several immune cells including lymphocytes, macrophages and dendritic cells. Gut probiotic bacteria like Lactobacilli have been shown immunomodificatory effects in the progression of atherogenesis. Some Lactobacillus stains can upregulate the activity of regulatory T-lymphocytes, suppress T-lymphocyte helper (Th) cells Th1, Th17, alter the Th1/Th2 ratio, influence the subsets ratio of M1/M2 macrophages, inhibit foam cell formation by suppressing macrophage phagocytosis of oxidized low-density lipoprotein, block the activation of the immune system with dendritic cells, which are expected to suppress the atherosclerosis-related inflammation. However, various strains can have various effects on inflammation. Some other Lactobacillus strains were found have potential pro-atherogenic effect through promote Th1 cell activity, increase pro-inflammatory cytokines levels as well as decrease anti-inflammatory cytokines levels. Thus, identifying the appropriate strains is essential to the therapeutic potential of Lactobacilli as an anti-atherosclerotic therapy.

Trimetazidine in conditions other than coronary disease, old drug, new tricks?

Trimetazidine (TMZ) has traditionally been used as an anti-ischemic drug for coronary artery disease by selectively inhibiting the mitochondrial long-chain 3-ketoacyl-CoA thiolase. Recently, new applications for this therapy have been investigated. This article reviews alternative uses for TMZ in non-coronary artery diseases, such as non-ischemic cardiomyopathy, sepsis, myocardial dysfunction induced by anti-cancer drugs, diabetic cardiomyopathy and contrast-induced nephropathy.

Association between serum 25-hydroxyvitamin D and carotid atherosclerotic plaque in Chinese type 2 diabetic patients.

In this study, we investigated the distribution of vitamin D and its association with carotid atherosclerotic plaque (CP) in Chinese type 2 diabetic (T2D) patients. We performed a cross-sectional study in 210 T2D and 94 age- and gender-matched nondiabetic patients during winter months, by determining serum 25-hydroxyvitamin D (25(OH)D) levels in both diabetic and nondiabetic controls. We carried out measurements of B-mode ultrasonography of carotid arteries in each T2D patient. The 25(OH)D concentration was 26.25 nmol/L among the T2D patients. About 93.3% T2D patients suffered from hypovitaminosis D. First, we found a clear inverse correlation between the 25(OH)D concentration and CP (P <0.001). Second, an association between 25(OH)D and macrovascular disease was significant (P = 0.005). In multivariate logistic regression analysis, decreasing 25(OH)D concentration was markedly associated with CP in T2D patients. Third, after adjusting for the confounding factors, we also observed a positive correlation between low levels of 25(OH)D in T2D patients with CP, when the following parameters were measured: old age (odds ratio [OR] = 2.533, P = 0.013); smoking (OR = 3.872, P = 0.001); and high level of low-density lipoprotein (LDL) cholesterol (OR = 2.776, P = 0.009). Thus, we concluded that high prevalence of hypovitaminosis D exists in Chinese T2D patients. Further, we found a significant association between low concentration of serum 25(OH)D and the existence of high body mass index, and high circulating LDL to be substantially positive predictors of patients with CP in T2D.

Cholesterol pericarditis associated with rheumatoid arthritis: A rare case report.

BACKGROUND: Cholesterol pericarditis (CP) is a special type of pericarditis. It is characterized by chronic pericardial effusion with high cholesterol concentration and with or without the formation of crystals in pericardial effusion. METHODS: In this case report, we described a 74-year-old male with massive pericardial effusion. He presented with no symptoms. However, he had 8-year history of rheumatoid arthritis medicated with methotrexate, celecoxib, and prednisone, and 5-year history of hypertension medicated with amlodipine besylate. On admission, transthoracic echocardiography revealed a large pericardial effusion. RESULTS: We performed pericardiocentesis for this patient and a lot of cholesterol crystals were found in pericardial effusion under the microscope. A successful operation of thoracoscopic pericardiectomy was proceeded, and the diagnosis was confirmed by surgical pathology. The patient was well recovered and discharged on the tenth day after surgery. It could be predicted that pericardiectomy under video-assisted thoracoscope could be a promising therapy for CP. CONCLUSION: Rheumatoid arthritis may cause CP with no symptoms. Pericardiectomy could be a promising therapy for CP.

Treatment strategy for treating atrial-esophageal fistula: esophageal stenting or surgical repair?: A case report and literature review.

INTRODUCTION: Atrial-esophageal fistula (AEF) is a rare severe disease, which may be associated with radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) or intraoperative radiofrequency ablation of atrial fibrillation (IRAAF). CLINICAL FINDINGS: We reported a case of a 67-year-old man with AEF following RFCA of AF, who treated with esophageal stenting and surgical repair. OUTCOMES: He was attacked by out-of-control sepsis and infectious shock after surgery and died. LITERATURE REVIEW: We analyzed 57 relevant articles about AEF from 2003 to 2015 by searching PubMed database. According literatures, the most common symptoms were fever, rigor, sepsis, and neurologic symptoms. Chest computer tomography (CT) and contrast enhanced CT may be the reliable noninvasive diagnosis methods because of high sensitive for AEF. CONCLUSION: Make a definition diagnosis in time with early primary surgical repair may save their lives. Conservative treatment or esophageal stenting alone may not be a better choice for AEF patients.

Association of blood pressure level with nonalcoholic fatty liver disease in nonhypertensive population: Normal is not the new normal.

The functional crosstalk between nonalcoholic fatty liver disease (NAFLD) and hypertension has been reported by some literatures; however, in nonhypertensive individuals, there is no article describes the characteristic of NAFLD. In this study, we aimed to determine the strength of the association between NAFLD with normal blood pressure (BP) in nonhypertensive individuals. This cross-sectional study was conducted in the sixth Affiliated Hospital of Wenzhou Medical University, from October 2007 to December 2011. In brief, 24,200 subjects were enrolled to participate in the survey. Among those subjects, there were 5305 enrolled subjects, those with filling the diagnostic criteria for NAFLD (21.9%; 4803 males and 502 females). Nonhypertension was identified in 17,403 (71.9%; 8179 males and 9224 females). The PR% of NAFLD for the systolic blood pressure (SBP) in quartiles 1 to 4 was 10.83, 12.55, 20.38, and 19.97. SBP, diastolic blood pressure (DBP), sex, age, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, fasting plasma glucose, uric acid, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol are closely associated with the risk for NAFLD. SBP (odds ratio [OR]: 1.092, 95% confidence interval [CI]: 1.030-1.158; P < 0.05) and DBP (OR: 1.157, 95%CI: 1.094-1.223; P < 0.05) were found to be independent risk factors for NAFLD. Our analysis indicates that BP is significantly associated with NAFLD in nonhypertensive individuals; SBP and DBP are found to be independent risk factors for NAFLD.

Silibinin: a potential old drug for cancer therapy.

INTRODUCTION: Silibinin is mixture of flavonolignans extracted from milk thistle and often has been used in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol and hepatitis and gall bladder disorders for its antioxidant and hepatoprotective properties. Areas covered: However, increasing evidence suggest that silibinin is not solely limited in the treatment of these diseases. Further research suggests that silymarin may function diversely and may serve as a novel therapy for cancer therapy, such as lung cancer, prostatic cancer, colon cancer, breast cancer, bladder cancer and hepatocellular carcinoma by regulating cancer cells growth, proliferation, apoptosis, angiogenesis and many other mechanism. Expert commentary: In this review, in order to provide potential new treatment for these cancer, we summarize the recent anti-cancer findings of silibinin in these cancer and clarify the mechanisms of this effect.

[Preliminary clinical experience on radiofrequency catheter ablation of right-sided accessory pathway guided by Ensite-NavX navigation].

OBJECTIVE: To explore the feasibility and methodology of radiofrequency catheter ablation (RFCA) guided by 3D navigation system (Ensite-NavX) for right atrioventricular accessory pathway. METHOD: Thirty-three cases of right accessory pathway atrioventricular reentrant tachycardia including 16 cases in right free wall, 3 in right middle septum, 14 in right posterior septum; 23 cases of dominant accessory pathway and 10 cases of concealed were treated by RFCA guided by NavX navigation. NavX navigation modeling method or spatial localization method was exploited to locate target positioning. RESULT: All patients were successfully ablated without serious complications. Among them, 25 cases were operated without exposure to X-ray, 7 patients were exposed for several seconds to verify catheter position, 1 case in right free wall was ablated under X-ray combined with Swartz sheath ablation. CONCLUSION: Nonfluoroscopy or less fluoroscopy RFCA for right atrioventricular accessory pathway with Ensite-NavX is safe and feasible, modeling or spatial orientation method are helpful to locate the ablation target positioning.
